HARRIS TAYLOR, on Wl-IITE WRIGHT, TEXANS.

SPECIFICATION forming part of Letters Patent No. 503,065, dated August8, 1893.

Application filed April 5 1 To all whom it may concern.-

Be it known that I, HARRIsTAYLoR, a citizen of the United States,residing at White Wright, in the county of Grayson and State of Texas,have invented anew and useful Nut-Lock, of which the following is aspecification.

This invention relates to that, classof nut locks which are especiallyadapted to be employed at railroad rail joints, in connection with thefish plates, and comprises aslotted locking plate adapted to normallyrest between two nuts and capable of being removed from looking positionbetween the latter. The object of my invention is to provide a simpleand improved nut lock of-- this character, which will possess advantagesin point of simplicity and inexpensiveness in construction, ease ofoperation, effectiveness,"durability, and general efficiency, and inwhich all the elements or parts are permanently retained together.

To these ends, my invention consists in certain details of constructionand in the combination and arrangement of parts, substantially as hereindescribed and particularly pointed out in the claim. 1

In the draWings:-Figure l is a perspective view of my improved nut lockin its entirety. Fig. 2 is a side elevation, showing the device inlooking position. Fig. 3 is a correspond ing view showing the device inopen position to permit the removal of the nuts. Fig. 4 is alongitudinal horizontal sectional View of my improved nut lock, taken onthe line o:0c, Fig. 2. on the line yy, Fig. 2. Fig. 6 is a verticalsectional view, taken on the line zz, Fig. 2. Fig. 7 is a detailperspective View, the smaller plate being broken away to show the underplate in detail.

Corresponding parts in all the figures are denoted by the same lettersof reference.

Referring to the drawings, A designates the under plate, which ispreferably formed of metal and provided at its ends with the bolt holesa, a and at its center near the top with a projecting fixed rivet, A,comprising the shank a and the flat disk a forming the rivet-head.

B designates the smaller outer plate, which in my invention ispermanently riveted to Fig. 5 is a corresponding view taken 893. vSerial No.469,185. (NomodeL) the larger inner or base plate A and permaportion B, the main portion B and the vertically-extended arm B beingpreferably relatively square or rectangular in shape. In the bodyportion B isformed a longitudinal slot, b, extending nearly from end toend, which slot is intersected by a short vertical slot, 19 provided inthe projecting arm B the shank a of the permanent rivet A beingaccommodatedby the slots. The slot 1) b is narrower than the flat disk aforming the rivet-head, so that the latter circumferentially projectsover the face of the outer plate B at the sides of the slot and preventsdisengagement or detachment of the plate B from the base plate A. Byreason of this permanent connection of the plates B and A, in connectionwith the flat disk a forming the rivet-head and thelongitudinally-extended slot b and short intersecting slot b the plate Bmay be lifted or elevated vertically and then turned up to a position atan angle to the plate A, as illustrated in Fig. 3 of the drawings,toenable the removal of the nuts.

In practice, the plate A rests against the .fish plate, 0, the boltholes a a receiving the bolts, D D, and the smaller outer plate Bnormally rests down between the nuts, E E, and thus locks the latter inposition in the usual manner. When it is desired to remove the nuts, theplate B is elevated or lifted until the shank of the permanent rivetpasses from the short slot 19 to the longitudinally-extended slotb',.when the plate B is turned pivotally upon the rivet to a position atan angle to the plate A, when the nuts are perfectlv free and may beremoved without-separatiolr of the plate B from the plate A, the formbeing permanently riveted and retained in connection with the latter andby reason of my improved construction and arrangement not liheing at anytime necessarily removed thererom.

Having thus described my invention, I claim and desire to secure byLetters Patcut-- The herein described improved nut lock, comprising theunder or base plate, A, having the permanent rivet consisting of theshank a and the flat cylindrical disk a forming the rivet head; and thesmaller outer plate, B, permanently secured to the base plate by thecylindrical rivet head and pro-" videdwith the short vertical slot 5 andthe longitudinally-extended horizontal slot 12' extending nearly fromend to end of the body portion of the plate B, said slots being liar-irower in width than the diameter of the per-f manent cylindrical rivethead; whereby the smaller outer plate is permanently connected with thebase plate and is adapted to be turned at an angle thereto by means ofthe longitudinally-extended slot, the whole forming 20' a completedevice in which all the elements or parts are permanently securedtogether but are adjustable with relation to each other; substantiallyas set forth.

In testimony whereof I aflix my signature in z 5
